To aZZ whom it may concern.-

Be it known that I, EDWARD GREEN, baronet, a subject of the Queen ofGreat Britain, residing at WVakefield, Yorkshire, England, have inventedcertain new and useful Improvements in or. Connected with HeatingApparatus, (patented in Great Britain, No. 18,086, August 3, 1897,) ofwhich the following is a specification.

This invention has for its object arranging valves within the boxes orentry and exit pipes of a fuel-economizer in such manner that all thetubes. may be simultaneously charged with the supply-water or the rodsbe moved so that the valves may close against the flow of thesupply-water except to the first or to the combined first and secondvertical tubes of a row of such tubes, the valves being brought againstpartitions in the boxes or pipes by a push-in or draw-out motionimparted to the rods by screw or other means from outside the boxes orpipes, the valves for the time being located permanently or temporarily,according to circumstances and as desired. I

The boxes or supply-pipes, with my shiftable valve and rod arrangementwithin them and horizontally both at top and bottom, may have verticaltubessay six or moreand constitute a set ready for being fitted into thefiueway of a furnace for heating the water in such boxes or pipes andtubes previous to its use-say for the heating of feed-water for aboiler-01 if the boxes or the pipes containing the valves and rods beprovided with side branches other boxes or pipes without valves androds, but having sockets with other vertical tubes, can be secured tothem to constitute series or nests of vertical tubes up or down orthrough which the water can flow to the series or nests of tubes, withtheir transversely-arranged boxes or pipes, in order that the transversebranch box or pipe of one row of vertical tubes or two of such rows ofvertical tubes may be collectively charged with the supply-watenor thenext row or the next two rows and its or their respective transverseboxes or pipes by. the arrangement of the valves and rods in the supplyboxes or pipes, the next adjoining row or next two adjoining rows ofvertical tubes, with their boxes or pipes, can be collectively chargedwith the supply-water before the Water flows in the reverse directiondown or up the next row, series, or nests of vertical tubes and theirrespective transverse boxesor pipes, or

by shifting the valves and rod of one box or pipe to the requisiteposition with relation to the position of the valves and rod of theother box or pipe in or to which the tranverse boxes or pipes havingvertical tubes affixed the whole of the tubes of one row may be upflowtubes and the next row of the next transverse box or pipe the downfiowfor the water, and so on alternately, or by the shift of the valves twoof such transverse boxes and two rows of vertical tubes may be forupflow of water and the next transverse boxes or pipes and verticaltubes connecting them be for the downfiow of the water, and so on inrows transversely alone or in conjunction with other vertical tubes ofthe lowerfor of the upper valve box or pipe. Said valve boxes or pipescan be arranged at diametrically opposite corners of a stack of boxes orpipes and tubes, and the connection between one set or series of tubesmay be by branch pipes, which may be arranged according to any desiredarrangement for the flow or passage of water.

My invention will be more fully understood by reference to the annexeddrawings, in

which t Figure 1 shows in sectional elevation top and bottom boxes orpipes provided with internal ribs and with valves on rods set inposition for water to flow up all the tubes simultaneouslyand to theupper box and away through the outlet. Fig. 2 represents in verticalsection the same boxes or pipes and tubes with the valves movedalong forthe supply-water to flow up the first tube and down the next tubes,andso on in succession to the outlet; Fig. 3, a similar vertical sectionalelevation of the same boxes or pipes and tubes with the valves moved forthe water to flow up the first two tubes and down the next two tubes,and so on to the outlet orifice, as indicated by the arrows; Fig. 4, asectional elevation similar to Fig. 1, except that the ribs in the boxesor pipes are of about three-quarter segments of a circle only, the otherfourth being of the box or pipe itself, on which the valves and rods aresupported pacity available for fitting them.

between the end caps of the boxes or pipes; Fig. 5, a sectional plan oflower and upper boxes or pipes having the valves arranged forsingle-tube flow into horizontal valveless boxes or pipes settransversely, which have branches for vertical tubes, all the tubes ofeach transverse rowbeing alternately for upfiow and downflow insuccession by the arrangement of the valves in the upper box and in thelower box, respectively; Fig. 6, a side elevation, partly in section, ofa lower valve box or pipe, lower transverse valveless boxes or pipes,upper valveless boxes or pipes with vertical tubes connecting, and uppervalve box or pipe for return of water down each alternate row of tubes,of which there may be any number to suit the extent of ca- This view istaken through the linesoc 5c of Fig. 7. Fig. 7 is an end elevation oflower and upper boxes arranged transversely and provided with verticaltubes for flow from and to the valve containing pipes, these being atdiametrically opposite portions of the structure, as before explained.

Similar letters of reference in the several figures indicate the sameparts.

A is the water-inlet pipe; 13, lower box or pipe; 0, vertical tubes setin sockets D of the lower box B 5 E, upper box or pipe, with sockets Ffor upper ends of tubes 0; G, valves in lower box or pipe; H, valves inupper box or pipe, said valves G H being on rods I J, operable byhand-wheels K L, as desired. The rods I J are screw-threaded near oneend and work in threaded sockets M N of the inner ends of the boxes orpipes B and E, where each has a gland P to make the joint watertight,the opposite or outer ends of the rods being in cup-caps Q of the ends.

R R are ribs in the boxes or pipes B E, into which the valves can bemoved when the hand-wheels K L are turned to close some of the passagesand to open others, according to the desired direction of flow.

S is the outlet for the heated water.

T is the blow-off opening in the lower box or pipe in relation to eachor to a series of vertical tubes, or one blow-off can be common to allthe vertical tubes.

U U are lower transverse boxes or pipes, connected at right angles bysockets V V to the lower valve box or pipe 13, and O O are verticaltubes therefrom.

W W are the upper transverse boxes, connected by sockets X X to thevertical pipes O and also by sockets Y Y with the upper valve-box E.

In all the figures I have shown that the supply-water enters atthe lowervalve box or pipe; but it can be entered at the outletorifice S, and inthat case the water would flow down the first vertical tube and thenrise up the other or others, according to the disposition of the valvesin the valve boxes or pipes.

What I claim, and desire to secure by Letters Patent, is-

The combination, in a heating apparatus, of vertical tubes 0, upper andlower horizontal pipes E and B connected, respectively, with the upperand lower ends of said tubes and provided internally, in juxtapositionto, and at points between the ends of the vertical tubes, with internalribs R constituting valve-seats, lengthwise-movable rods J and I,located in the horizontal pipes, and valves II and G, each rod having aseries of attached valves located, respectively, between two of the saidvalve-seat ribs, and some of the valves constructed and arranged,respectively, to close against either one of two adjacent valve-seatribs to change the direction of the flow of the supply-water,substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
